This invention relates to a paratus for the convenient heating andpensing of water for use in internal baths, douches, enemas, etc.- The(principal object of the inven- I tion is to provi e an apparatus whichmay be convenientl mounted in any suitableposition or bui t in as apermanent fixture and which can be conveniently operated toautomatically heat and dispense a certain quantity of water.

A further object of the invention is to provide, if desired, fordelivery of antiseptic agents to the water.

The apparatus comprises essentially .a

5 water receptacle, means controlled b man ual operation for fillingsaid receptac c with water at the desired temperature, and meansoperable either automatically or manually for shutting off the supply ofwater and also shutting ofi the heating device, whereupon the receptaclemay be emptied through the usual hose or other outlet means. Theapparatus also preferably includes manually operable means fordelivering a measured quantity of antiseptic, or other li uid a ant,

to the water in the receptacle. Ot er a' vantageous features of theapparatus will beapparent from the following descri tion.

The accompanying drawings illustrate 8 embodimentsof the invention, andreferring thereto:

Fig. 1 is a vertical section on line 1-1 in Fig. 2.. a

FFig. '2 is a vertical section on line 2-2 in ig. 1. r c

Fig. 3 is a partial section on line 3-3 in Fig. 1, with part of theouter casing wall broken away.

The apparatus is shown as comprising an outer casing having front wall1, rear wall 2, top 3 and side walls 5' and 6. The front wall may ifdesired be hinged or otherwise mounted to permit opening or removalthereof for the purpose of inspecting, cleaning, or replacing any of theinside parts. A door 7 provided with mirror 7 may also be hinge'dlymounted in front of the casing, so as to give the cabinet an external apearance similar to that of the ordinary medicine cabinet. Within saidouter casing is mounted a water receptacle 8, consisting forexample of arectan ar tank and supported on the casing as Indicated at 9. The waterinlet pipe 11 enters through the rear wall of the casingand is providedwith a valve 12 for opening and closing the same. Said pipe then assesdownwardly as indicated at.13 to ad acent the bottom of tank 8 where itopens upward- 1 into the bottom of a heatin device 15. aid heatingdevice comprises a lieating element consisting, for example, of anelectric heating coil 16 and means for causing the water deliveredthereto to pass in the form of a relatively thin lay er around saidheating unit so as to be heated thereby. For example the device maycomprise a cylindrical member 18 closed at the bottom as at 19 and openat its upper end, and another member having aninner closed cylinder 20fitting wlthin the tube 18 and an outer cylinder 21 extending downoutside the member 18 so as to cause the water delivered to the interiorof the member 18 to pass first u wardly in the space 23 between said memer and the cylinder 20 and hence close to the heating element, then overthe upper ed 6 of member 18, then downwardly in t e space 24 betweenmember 18and cylinder 21 and then out into the interior of receptacle 8.A thimble or sleeve of suitable refracto clay or the like may beprovided between eating element 16 and cylmder 20.

A cover or cap 26 may be fitted over the upper end of the heating deviceto provide a means of connection of the electrical conductors 27 to theheating element.

The electrical connections 27 for the heating coil may be connected tothe fixed or moving contacts of switch 30, while the other set ofcontacts ma be connected by wires 31 to any suitable e ectric power suply system such as the ordinary electric lig ting system in a house. Themoving contacts of switch and the operating member of valve 12 may bemounted upon a shaft 32 which is rotatably mounted in bearings "33. Saidshaft extends through a recessed portion 1' of the front wall of thecasing and is provided at its outer end with a knob or handle 34 formanual operation thereof. Said shaft is also provided with a catchmember having a lip or projection 36 adapted to be engaged and held by apawl 37 when the handle 34 1s operated to open valve 12 and close switch30.

2 as indicated at 43, to any suitable drain means, so as to permitoverflow of water until the same is treated to the desired temperature,and a thermometer 44 may be mounted in suitable osition in front ofreceptacle 8, with its bul projecting into said receptacle. The frontwall 1 of the outer casing may be cut away in frontof said thermometerto permit reading of the water temperature.

Within the outer casing and below receptacle 8, is mounted a windingreel 45 upon which is wound a rubber hose 46 having a nozzle 47 at itsfree end. The inner end of hose 46 is connected to a hollow trunnionmember 48. Outlet pipe leads from the bottom of receptacle 8 tofitting51 which engages in hollow trunnion 48 so as to cause water topass from pipe 50 into said hollow trunnion and thence into the hose 46.Trunnion 48 and fitting51 maybe provided with bevelled faces asindicated at 52 and a spring 53 may be provided exerting an endwisethrust on the winding reel so as to holdsaid parts in tight engagement.The winding reel may be rotatably mounted by means of the abovedescribed hollow trunnion and by means of a bearing 55 fitting over afixed shaft 56.v A rewinding spring 57 may be connccted at one end tothe shaft 56 and at the other end to trunnion member 48 or to the reelitself so as to rotate said reel in a clockwise direction (in Figs. 1and 3) and re-wind the hose 46 thereon. An opening 58 may be provided inthe bottom of the casing, through which the hose 46 may be drawn foruse, and a led e or shelf 59 may also be provided, upon which the end ofsaid hose and nozzle 47 may rest when not in use.

The means for automatically releasing the pawlmember 37 from catch means36 may be as follows. Said pawl member is shown as pivoted at 60 andhaving an arm 61 whose outer end is connected to an off-set arm 62 atthe top of a link 63, which is connected at its lower end to an arm 64pivotally mounted at 65. Said arm 64 may rest in an annular groove 66 onthe winding reel 45, the bottom of said groove being provided with a camor rounded projection 67 adapted to lift arm 64 upon rotation of saidwinding reel. In order to also permit manual release of pawl 37, the

arm 62 may also be connected to an arm 69. A lifting member 70 extendsbeneath arm 69 and is pivotally mounted at 71 and push button 72provided with an outwardly acting spring 73 is o erable to engage arounded portion 74 on li ing member 70 and swing sail lifting memberupwardly about its pivot 1. c

The means for delivering antiseptic or other liquid agent to the watermay comprise a receptacle or tank 76 adapted. to contain a quantity ofsuitable liquid antiseptic agent, said receptacle having a fillingopening 77 provided with cap 78, and being preferably of suflicient sizeto hold enough antiseptic agent for several operations of the apparatus.Pipe 79 leads from the bottom of receptacle 76 toa measuring device 80consisting of a cylinder 81 in which is mounted a plunger or piston 82.The stem 83 of said plunger extends upwardly through the cover 84 andthrough the top wall 3 of the outer casing and is provided at its upperend with a head or button 85 to permit manual depression of plunger 82.A small check valve 87, such as a swing check valve, may be provided inthe inlet pipe 79, said check valve being adapted to permit flow ofliquid from tank 76 into the interior of cylinder 81 while preventingflow in the reverse direction. Stem 83 may also be provided at its lowerend with a valve member 88 adapted to engage seat 89 when plunger 82 isin raised position and prevent communication between the portion ofcy1-. inder 81 above the horizontal partition plate 9.0 and the portionbelow said plate. A pipe 91 leads from the bottom of cylinder 81 towater inlet pipe 13. Spring 93 acts against member 94 to automaticallyraise stem 83 and plunger 82 to the position shown nponrelease of thedownward pressure thereon.

The operation of the apparatus above described is as follows Undernormal conditions when the apparatus is outof use, the receptacle 8 isempty,

valve 12 is closed and the switch 30 is open. To start the device inoperation handle 34 is turned in. a clockwise direction to the onposition as indicated in Fig. 3, until thecatch member 36 passes overthe pawl 37, which holds the shaft 32 in this position, at which timevalve 12 is opened and switch 30 is closed. The single manual operationof handle 34 thus serves both to turn on the water supply to thereceptacle and also to start the heating element 16 in operation.

The water then passes through pipes 11 and 13 to the interior of theheating device 15, thence upwardly in the annular space 23 and aroundthe heating element 16 and then downwardly through the annulanspace 24and out into thereceptacle. Due to such passage in a relatively thinlayer in close proximity to the heating element the water is quicklyheated'and delivered to the receptacle at the desired temperature. Incase the receptacle should become filled before it is desired to use thecontents thereof, the water will simply overflow through p'pe 42 andpass ofi through the drain means.

If it is desired to deliver an antiseptic or other liquid agent to thewater, the button 85 may be depressed, whereupon a measured quantity ofsuch agent is forced from the interior of cylinder 81 through pipe 91and is thoroughly mixed with thewater entering through pipe 13. Durinthe downward motion of lunger 82 the c eck valve 87 closes 'tightly ueto the pressurebeneathsaidplunger, until the plunger has passed belowthe leyel of pipe 79, after which a further quantlty of the antisepticor other agent flows from container 76 into cylinder 81 above theplunger 82. When the button 85 is released, spring 93 forces the(plunger'upwardly and the agent passes aroun .the s ace fact tiat returnoffsaid agent to tank 76 1s the edges of said plunger into beneath theplunger, due to the again prevented by check valve 87. The valve member88 then engages seat 89 to positively revent passage of any furtheramount of iquid from above said .valve into the water and also reventdi'fiusion of water back into the liquid abovesaid valve and beneath theplunger '82. I

When the water in receptacle 8 hasbeen heated to the desired temperatureas indicated by thermometer 44, the water supply and electriccurrent-maybe shut ofi either automatically or manually. If it isdesired to make use of the contents of receptacle 8 at once, the

hose 46 may be unwound from winding reel 45, the resulting rotation ofthe winding reel brm 'n the projection or cam 67. beneath arm 64 w liCacts through link 63 and arm 62 to release the pawl member '37 fromcatchmeans 36 and permit spring 40, acting on arm 39, to restore valve12 to closed osition and switch 30to open osition, at WhlCh time thehandle We claim:

1. A water heating and dispensing apparatus comprising a waterreceptacle, means for supplyin' water to said receptacle and for heatingt e water so supplied, means permitting overflow of water rom saidreceptacle untll the water in the receptacle reaches the desiredtemperature, outlet means connected adjacent the bottom of saidreceptacle and includln a hose wound upon a self-winding supplied,manually operable means for simulstaneously turning on the supply ofwater and the heating, means therefor, means causing the water supply tobe maintained and the heating means therefore to be kept in operationupon such movement of said, manually operable means, means permittingoverflow of water from said receptacle until the water in the receptaclereaches the desired temperature, outlet means connected adjacent thebottom of said receptacle, and manually controlled means forsimultaneously shutting off the supply of water and the heating, meanstherefor.
